Integrated, Non-Isolated, Point of Load,
DC/DC Power Modules:
4.5~5.5Vin and 7~13.2Vin, 0.8-2.5V/ 10Aout
The MCM12S10Q, 4.5~5.5V and 7V~13.2V input, single output, fully
integrated non-isolated point of load DC/DC converters are the latest
offering from a world leader in power systems technology and
manufacturing －Delta Electronics, Inc. This product family provides up
to 10A of output current or 33W of output power in an industry standard,
compact, IC-like, molded package. It is highly integrated and requires few
external components to provide the point-of-load function. Copper pads
on the back of the module in close contact with the internal heat
dissipation components provide excellent thermal performance. These
converters hence possess outstanding electrical and thermal
performance, as well as extremely high reliability under highly stressful
operating conditions. Operating over both the input voltage ranges 4.5V
to 5.5V and 7V to 13.2V, the MCM12S10Q supports an output voltage
range from 0.8V to 3.3V, set by a single resistor. The MCM12S10Q is
packaged in a thermally enhanced, compact (15mm x 15mm), and low
profile (3.5mm) over-molded package suitable for automated assembly by
standard surface mount equipment. The MCM12S10Q is lead free and
RoHS compliant.
